Chapter 388 The Graviton Projection
"So, this is it."

Gravity of relativity, and gravity of multidimensional field theory.

He needed only a slight transformation of the gravitational force of the multidimensional field theory to find that the two formulas were so similar that he couldn't even make any difference.

Then, some simple transformations were performed, so the two equations could be connected with an equal sign.

"Is this just a coincidence in physics?"

Lin Xiao couldn't help but admire in his heart.

This is equivalent to the theory of relativity and quantum mechanics, which were almost completely incompatible in the discussion of gravity, can now be connected with an equal sign.

Of course, although it is connected, what kind of physical meaning is contained in it still needs some discussion.

Although the current Lin Xiaoda can directly publish the equation he accidentally discovered, and he also believes that this is just an article in "Physical Review Letters", and it can easily set off a wave in the physics community.

However, with Lin Xiao's personality, he would not allow himself to publish it without even getting the meaning out of it.

Looking at this equation and the left and right formulas, Lin Xiao squeezed his chin. How to see the actual physical meaning from the mathematical symbols is a relatively common thing for an excellent physicist. After all, they originally It is to use mathematics to discuss physics. If they cannot understand the physical meaning, it will obviously hinder their research.

However, for Lin Xiao, seeing the meaning behind it is not the most important thing. The most important thing is whether he can make more deduction after seeing the meaning.

And at this very moment, that's exactly what he was doing.

Looking at the formula in front of me, although both sides of the equation are harmonious, but no matter what, as a person who has a deep research on physics, after being pleasantly surprised by the formula that has a relationship between the theory of relativity and the graviton, It's just a kind of awkwardness, of course, it's a kind of awkwardness out of habit, not the kind of awkwardness that feels that this formula is wrong.

In this way, after observing the equation carefully, Lin Xiao frowned slightly, and had some thoughts.

General relativity includes the classical Newton's law of universal gravitation within the framework of special relativity.

In general relativity, gravity is described as a geometric property of space-time, that is, curvature, and this space-time curvature is directly related to the matter in space-time, and its connection method is the Einstein field equation.

"Therefore, Einstein's description of gravity in the theory of relativity is presented by this Einstein's field equation."

【Gμv=Rμv-1/2gμvR...】

Lin Xiao wrote down this Einstein field equation on paper. The equation is very simple, but the various meanings contained in it are not simple at all.

"This is based on the definition of gravity under the general theory of relativity, and according to the multidimensional field theory, various dimensions are superimposed, and gravity...gravity..."

Lin Xiao groped for his chin, but his eyes became brighter and brighter.

He suddenly had a feeling of completely simplifying this problem.

"Just like the description of gravity under the general theory of relativity in the current physics community, an extremely heavy matter presses out a hole in the large network of space-time, and then other matter around this extremely heavy matter will start to circle this space. The pit surrounds."

As shown in the videos describing gravity on the Internet, there is a stretchy cloth, and then a big ball representing a star is put on it, and the big ball presses out a crater, and then throws it from the edge A few balls representing planets were entered, and these balls representing planets began to circle the big ball representing stars and began to circle around.

"But obviously, in our world, space-time is three-dimensional, and stars are also three-dimensional, so it is impossible for three-dimensional stars to press out a big net on three-dimensional space-time, but if gravity acts on our three-dimensional space-time from the perspective of four-dimensional What effect does it have?"

"And in fact, the academic community has always had this view."

That is to say, gravity should belong to the four-dimensional space, not the three-dimensional space they are in, so they cannot observe gravity in the three-dimensional universe.

"However, how can gravity interfere with our three-dimensional space from a four-dimensional perspective? Is there something in between that connects these two things?"

At this moment, Lin Xiao already felt that he was very close to that key.

"Contact... Contact..."

Lin Xiao's heart suddenly moved, and he had a bold idea.

"Perhaps, gravitons are like this?"

He started the derivation again.

This time, he integrated the graviton-like particle predicted in the standard model of multidimensional field theory.

Integral is the inverse operation of differentiation.

Derivation is the differentiation of the original function, and integration is to find the original function.

At this time, what Lin Xiao has to do is to find out the original function of the graviton in this three-dimensional space.

This is a slightly complicated indefinite integral problem. Of course, in Lin Xiao's hands, this complexity can become simple.

And with the completion of this step, he saw an astonishing result.

After the integration, the graviton, let’s call it the graviton in the four-dimensional space, is actually related to his previous equation.

Lin Xiao's eyes showed surprise, and then he was relieved.

"So, the gravity in the three-dimensional space is actually the shadow of the four-dimensional graviton in the four-dimensional space..."

"And the graviton-like thing I predict in the standard model of multidimensional field theory is its shadow."

The tone of his statement meant his affirmation of the result.

Just like the shadow of a person, it belongs to the projection of a three-dimensional object onto a two-dimensional surface, and the projection of a four-dimensional object is naturally projected onto a three-dimensional surface.

"It's just that, because it involves high-dimensional particles, it makes our observation difficult."

"Then, this is a good solution."

A smile appeared on Lin Xiao's face.

Once, he used low-dimensional to spy on high-dimensional, but now, he even found the connection between high-dimensional and low-dimensional.

At the same time, it is conceivable that which other particles also belong to this kind of projection?
Lin Xiao can easily think of one, and that is the neutrino.

After all, neutrinos are also difficult to observe, elusive and difficult to detect.

"Okay, let's not talk about these, let's sort out the papers first."

It just happened to bring an important result to his multidimensional field theory again.

Although his multi-dimensional field theory has been born for several years, there are not many people who have studied it, but there are not many major achievements like this.

So it's up to him, the founder, to drop another depth charge to revitalize this piece of water.

……

The review speed of "Physical Review Letters" is notoriously fast, especially the speed of rejection.

Of course, when the contributors are famous physicists in the world, they receive the manuscript very quickly.

Therefore, when Lin Xiao's paper was submitted, the editorial department quickly completed the review. First, they were extremely amazed by the content in it, and then published the paper that surprised them all in their next page. in a journal.

"Physical Review Letters" is mainly known in the physics community for its short length and important content. In a word, most of the papers are relatively short and concise, so there are many physicists who subscribe.

And when Lin Xiao's paper was seen by physicists, the entire theoretical physics community exploded immediately.

Connect relativity and gravitons?Also follow the standard model of multidimensional field theory?

Gravity is the product of four-dimensional space in three-dimensional space?The graviton in their universe is the projection of the graviton in the four-dimensional space?

These sci-fi-sounding words are not at all sci-fi in Lin Xiao's paper, and those sci-fi words basically come from their physics circle.

Therefore, Lin Xiao's paper also made all physicists feel crazy.

But from a mathematical point of view, no one questions the correctness of it.

After all, Lin Xiao’s derivations are all rational and orderly inferences, not based on additional theories for perfection, just like the description of gravitons in the Standard Model, which was originally determined by the physicists who originally determined the Standard Model. Introduced to improve the model.

As a result, a heated discussion was launched in the physics community, many famous physicists, especially some Nobel physicists.

"I have to admit that each of Professor Lin's papers is so amazing. As a physicist who studies quantum mechanics, I support Professor Lin's results."

"In any case, Professor Lin's thesis has opened up a possibility for us. I think we are now one step closer to the final answer to gravity. As for what is the final answer, it is naturally up to us." In the collider, see the fleeting gravitational interaction force. 』

"Oh, my God, the two upstairs are both Nobel Prize winners, I really learned a lot!"As a Ph.D. student in physics, I can only tremble. Of course, no matter what, Professor Lin will always be my idol.』

"Professor Lin is still very good, and he has made such a major achievement in multidimensional field theory. It feels like Einstein's theory of relativity. Einstein almost developed relativity to a position equal to quantum mechanics alone. level, and now Professor Lin is also doing such a thing, right? 』

"That's true, even though I can't understand even one of Professor Lin's papers"

Among the many speeches, there are quite a few who maintain a high opinion of Lin Xiao's paper, but in these speeches, a refuter who studies relativistic physics appears, and this relativistic physicist is also a well-known physicist. Although he did not win the Nobel Prize, he did not miss other heavyweight awards in physics.

"Hey, no matter how fancy you say, I don't dare to imagine the existence of gravitons. Although Professor Lin connected the existence of gravitons with the theory of relativity, from another perspective, wouldn't this still make people Does Relativity Completely Break Down? 』

Of course, other physicists also responded to this well-known physicist's speech: "Oh!Old Zeke, you can’t think like this, it’s just an equal sign now, but it’s inevitable that we won’t be able to find a perfect method to make the theory of relativity and graviton more harmonious?After all, they are all connected now, just like when you chased your wife, you also took your time, you have to connect first, and then slowly get closer.』

"My wife and I met in a bar. We got drunk together and then we got it all over. There is no such process of getting closer as you mentioned."

"..."

In this way, more and more physicists are discussing this matter, until finally, the physicists who study quantum mechanics are very convinced of Lin Xiao’s result, but for those physicists who study the theory of relativity, they Although they recognized Lin Xiao's thesis, they still said that they would still not believe the result if there was no experimental result to prove it.

As for the experimental results they want to see, it is natural to directly or indirectly observe the existence of gravitons in the experiment.

And this is the most critical point in this matter.
